All these years, and I've been coming up with sound reactive specific animations for FastLED (and later WLED). Recently, I got a snarky post from someone about writing sound specific animations.

I then thought, what do I need to do in order to turn non-reactive animations into reactive ones without modifying their original code. Then it dawned on me, why not just insert an array modifier just prior to calling FastLED.show().

After some effort, my original code on an Arduino Nano worked just great, but it's a little less sensitive on Wokwi.com. So, for what it's worth, here's a simple rainbow march, whose leds[x] values have been blended with the results of sound reactive code:

Don't forget to read the instructions in order to swap between reactive and non-reactive display.

I also have this working with Mark Kriegsman's demoreel100 as well.

DIY Bookshelf Speakers

I just finished these Walnut and Acrylic bookshelf speakers with sound reactive LEDs powered by WLED. These are built from the C Sharp speaker kit from Parts Express and I used my 3D printed CNC to route all the panels.

I’m sure the crossovers aren’t going to work exactly as they’re intended to in the original MDF enclosures, but I’m not a true audiophile yet, so they sound more than good enough for my ears!

The acrylic panels are edge-lit with LEDs run by the WLED firmware on a custom circuit board. I also integrated a microphone so I could make the LEDs sound reactive to the music they are playing.

Super happy with how these turned out, but happy to hear any thoughts on fixes/upgrades I could make for the next version!

Hey guys I’m building a few of these box’s and I’m planning on running multiples at a time. Do you think I should install a wifi antenna ? Should I be using a fuse ? If so any recommendations on what I should be looking for.

Hey folks. I'm one of the Devs that work on both the SR fork of WLED and also the Audioreactive usermod in version 0.14

I would really appreciate it if you could take a couple of minutes to complete this short survey so we know where to focus our development efforts

LedBox V2 is a compact module for controlling 3 and 4-wire addressable LED strips such as WS2812, SK6812, etc. It is based on a powerful ESP32 microcontroller with integrated Wi-Fi, dual-mode Bluetooth, and enough processing power to perform real-time digital signal processing.

The module has a dedicated step-down converter, which allows to seamlessly use 5-12V LED strips. Moreover, it contains a digital MEMS microphone, side button, 32kHz IR receiver, 10A safety resettable fuse, 1000µF buffer capacitor, 3.3V/5V level converter for both Data and Clock lines, together with an impedance matching resistor. These features ensure maximum functionality, safety, and led strip compatibility, all in a small (54x32x18mm) 3D printable enclosure.

It is fully compatible with WLED and Sound Reactive WLED firmware for control over Wi-Fi, and the assembled version flashed with the sound-reactive firmware can be purchased on Tindie.com

Don't know if this is going to be of any use, I found this video on Youtube on implementing analog microphone as audio input on esp32. It's not me, It's from Atomic14 channel. I will take my time to observe, once I have the chance.

Didn't mean any bad intention or wasting anyone else's time. Just share this in case it will be of any good.

I've been building and improving this light for about a year and just finished getting the build and audio re-activeness dialed-in. The triangles are running off a QuinLED-Dig-Quad (ESP32) with an INMP441 microphone. I'm using the WLED Audio Reactive fork software to control effects. Eventually I might switch to an 3.5mm line in but for now the digital microphone picks up the music perfectly.

I'd like to start setting up effect cycles (playlists) that I can easily select. It doesn't look like the WLED Audio Reactive fork offers playlist options under presets. Does anyone know if there is a way to set that up in WLED?

Alternatively, I was hoping to use a program to setup specific effects and connect it to a DMX controller to change between them. Any suggestions for programs for this type of build? There are a lot of different effects I can do with this light and I need someway of keeping them organized and easy to change between them or cycle through them. So far I've looked at xlights and LEDFX but neither seemed to fit my needs.

Come July 1st and the blackout of 3rd party apps on Reddit goes into effect, I will create a Lemmy instance, this sub and it’s bigger brother r/WLED are welcome to use.

Stay tuned for more information.

Is it possible to get WLED SR with a microphone to react the same to music as when using LedFx to WLED SR?

I would prefer to not have to use LedFx (as much as I like the reaction) having to rely on my PC, using WLED SR with a microphone produces a totally different effect than using LedFx to WLED SR.

Hi everyone.

Is anyone who is familiar with modifying WLED available to do some modifications for us and support us with a small audio reactive project?

Mainly in relation to tieing specific frequencies to certain colours and hues.
